Point-to-point encryption

There also exist payment solutions based on end-to-end encryption, implying the highest level of confidentiality for the transferred data.

A device that is part of a PCI-validated P2PE solution uses an algorithmic calculation to encrypt the confidential payment card data.

[citation needed] The keys for encryption and decryption are never available to the merchant, making card data entirely invisible to the retailer.

A true P2PE solution is determined with three main factors: End-to-end encryption as the name suggests has the advantage over P2PE that card details are not unencrypted between the two endpoints.

If the endpoints are a PCI PED validated PIN pad and a POS acquirer, there is no opportunity for the card details to be intercepted.
